Vehicle control apparatus and method for controlling the same, and vehicle control system

A vehicle control apparatus calculates an approximation equation of an N-th degree function as a movement trajectory of a preceding vehicle from at least two pieces of relative position information. The vehicle control apparatus also calculates a coefficient of a predetermined degree in each approxi...

Beschreibung
Zusammenfassung:A vehicle control apparatus calculates an approximation equation of an N-th degree function as a movement trajectory of a preceding vehicle from at least two pieces of relative position information. The vehicle control apparatus also calculates a coefficient of a predetermined degree in each approximation equation, and in the calculation of the coefficient of the predetermined degree and uses an approximation equation calculated from the at least two pieces of relative position information acquired when setting a retrospective range to the same range or a narrower range compared to when calculating a coefficient of a relatively low degree when calculating a coefficient of a relatively high degree. The vehicle control apparatus also uses an approximation equation when setting the retrospective range to a narrower range compared to when calculating a coefficient of a lowest degree at least when calculating a coefficient of a highest degree.
